; 
;  * Protocol control block for an active
;  * instance of a UNIX internal protocol.
;  *
;  * A socket may be associated with an vnode in the
;  * file system.  If so, the unp_vnode pointer holds
;  * a reference count to this vnode, which should be irele'd
;  * when the socket goes away.
;  *
;  * A socket may be connected to another socket, in which
;  * case the control block of the socket to which it is connected
;  * is given by unp_conn.
;  *
;  * A socket may be referenced by a number of sockets (e.g. several
;  * sockets may be connected to a datagram socket.)  These sockets
;  * are in a linked list starting with unp_refs, linked through
;  * unp_nextref and null-terminated.  Note that a socket may be referenced
;  * by a number of other sockets and may also reference a socket (not
;  * necessarily one which is referencing it).  This generates
;  * the need for unp_refs and unp_nextref to be separate fields.
;  *
;  * Stream sockets keep copies of receive sockbuf sb_cc and sb_mbcnt
;  * so that changes in the sockbuf may be computed to modify
;  * back pressure on the sender accordingly.
